To all whom it may concern Be it known that I, EDMUND S. CHURCH, acitizen of the United States, residing at Dayton, in the county ofMontgomery and have invented certain new and useful Improvements in Cashand Credit 3 Registers, of which I declare the following to be a full,clear and exact description.

Many commercial establishments are at present using mechanical devicesto assist in auditing and keeping track of the various transactions ofthe business. One of the most successful systems involves the use of aregistering mechanism having means for adding and listing thetransactions in succession and thereby providing at the end of abusiness period a complete list of sales made as Well as the total ofthe value of the sales. Many establishments employ what is tanned amultiple counter register, meaning' thereby one having instead of asingle totalizing device from five to ten counters enabling thereby asegregated analysis of transactions to be retained in the machine. Sucha mechanism provides for adding separately the sales of each clerk ordepartment or both and at the same time for listing each separate saletogether with a record of the salesman who made it or the department tothe credit of which it should be placed. Such a system is satisfactory,provided only a very limited number of separate summations are desired,but it is very diflicult to provide a machine having more than a verymoderate number of such registers. In one type of registering machinenow on the market the separa te counters or registers are mounted on arotatable carrier so that any one of them may be thrown into operativerelation with a series of operating racks. This machine however is opento the criticism that only one counter may be used at a time and if itis desired for example to add the sales made by each clerk and the salestion aims to greatly increase the capacity of such machines so muchjsoin fact that any desired number of registering or total retalmng devlcesmay be employed. In many commercial establishments the problem of pre- "greatly to enlarge the field of usefulness of class of businesstransactions. It is of course possibleto use a cash register having acharge counter on which the amount of credit sales may be entered butthis does not serve to indicate which customer should be debited with anamount, nor does it when a payment on account is made serve to designatethe customer who should be credited therewith. It has also been proposedto provide a cabinet having many small drawers therein one for eachcredit customer and to insert in said drawers a slip bearing the recordof the amount of any credit sale. This system presents some advantagesbut is open to the charge that all additions of amounts must be madementally and also that the slips may easily be lost. This invention aimsto improve credit systems by providing a machine which may employ atotal retaining device for each customer.

Among the objects of the present invention therefore may be said to beto provide a machine with any desired number of total retaining deviceswhich may be distributed among the. clerks, departments, and creditcustomers. Each clerk will therefore have his own device which he may ifdesired carry with him, each department no matter how many there arewillhave its own total retaining device and sowill each credit customer.

A further object is to provide with such a machine a mechanism wherebythe total from any retaining device may be read at any time.

Another object is to provide a total retaining device for each customerwhereby the total of the account is always retained therein, said totalbeing obtainable without resetting the device at any time.

Another object is to improve the construction of adding and subtractingmachines by providing mechanism whereby if a payment on account is madeby a customer or if money is paid out by a clerk the amount thereof maybe subtracted from the proper total retaining device instead of addedthereto. This feature of this invention is not limited to use with thearticular total retaining device above referred to but may be used inthe ordinary type of adding machine with equally good results.

This invention in itsbroader aspects serves ited to stores of one kindor another but the mechanism described herein may be used not only instores but in many other kinds of business among which may be mentionedmerely building .and loan associations, in

a which case a total retaining device would be exact present total ofthe indebtedness without calculation.

The machine may also be used in keeping a continuous inventory of stockof any kind. In such use one total retaining device would be providedfor each article kept. in stock. When the stock of any particulararticle was increased, the number so added would also be added on theparticular retaining device and when requisitions on the stock werefilled the number of articles so taken away wouldbe subtractedtherefrom.

Only a few of many possible applications of the machine are thusreferred to but it will be clear that themachine may have a veryextensive use.

With these and incidental objects in view, the invention consists incertain novel features of construction and combination of parts, theessential elements of which are set forth in appended claims and apreferred form of embodiment of which is hereinafter specificallydescribed with reference to the drawings which accompany and form partof this specification.

Fig. 18 is a detail of the record carrying vices.

and Figs. 19 and 20 on the market but it is to be understood at theoutset that the invention is not limited to use with this type ofmachine but may in fact be used with many other varieties of adding andlisting machine. a

As above stated the invention contemplates the use of any desired numberof what may be termed total retaining devices which are separate anddetachable from the machine and which have therein denominationalelements for retaining the various en-v tries in the machine andidentifying elements for entering in the machine at each transaction arecord of the particular retaining device employed. 1

In the machine is provided a plurality of printing devices one for eachof the denominational elements of the retaining device and also for eachof the identifying elements th ereof. These, printing devices areadapted to be controlled in their movement at the outset of theoperation by the denominational and identifying elements of ,the totalretaining devices and when the said printing devices have been so moveda register is connected thereto and the printing devices then resetwhich resetting evidently serves to move the registering device to anamount equal to that previously in the retaining device. The amount ofthe transaction is now added to or subtracted from the registeringdevice by a novel mechanism and at the conclusion of this part of theoperation the register is again connected to the printing devices andreturned to normal position thereby again adjusting the denominationalelements of the total retaining device, but the adjustment now includesthe last item. When the register has been so returned to normal positionthe printing devices have been adjusted to the new position of thedenominational elements of the total retaining device and an impressionis then taken on a record material from the said printing de- Whendesired two impressions, one on a strip and one on a check or slip maybe taken. If at any time the standing of an account is desired the totalretaining device therefor may be inserted in the machine and the amountthereof printed without permanently. restoring the denominational elements to normal position. To provide for credit'transactions a slidabletable is used. on which a slip may be placed and the table drawn intothe machine in position for the printing devices to make an impressionon the slip. For other kinds of transactions the ordinary cash registercheck is or may be used. The record on the detail strip is intended toinclude the clerks or customers number determined b the identifyingelements, the amount of the present transaction, the total standing ofthe account and any desired information such for example as the date andconsecutive number of the transaction. I

As above stated applied to a well the invention is shown as known typeof machine which is described fully in the patent to Cleal and Reinhard580,378, April 13, 1897.

For a full description of the mechanism reference is made to this patentbut it may be generally stated as follows, reference being made to Figs.2 and 3. Groups of amount keys 21 serve to control the movement ofsegments 22 through latches 23 carp with a gear 38 in turn ried by saidsegments. The segments are mounted on' a main shaft 24 which shaftcarries tightly thereon a plurality of segments 25 one beside eachsegment 22. A latch 23 is pivoted at 26'on each of the segments and isbell cranked in form at one extremity having a by-pass pawl 27 and atthe other extremity being pivoted at 28 to a slide 29 carried in flanges30 of the segment 22. The slide 29 has a notch 31 at the rear endthereof adapted to be engaged by the projection 32 on each of thesegments 25. The keys when depressed are in the path of the bypass pawl27. The shaft 24 is oscillated through about at each operation by an arm33 connected to a link 34, this link being operated by an arm 35 on amain operating shaft 36 which is given a complete rotation in thedirection of the arrow at each operation. The shaft 36 is shown in Fig.2 and from said figure it will be seen that also rigid with the shaft isa gear 37 meshing driven by a large gear 39. The gear 38 is rigidlymounted on a shaft 40 which is also one of the operating shafts of themachine. The large gear 39 however is mounted on a stub shaft 41 andgears with a pinion 42 on a stub shaft 43. This pinion 42 is driven bythe main handle 44 which is given two complete rotations at eachoperation of the machine.

The gears 37 and 38 have twice the number of teeth of gear 42 and arethereby given one complete rotation at each operation. When the arm 35on Fig. 3 is rotated the segments 25 are oscillated until the projection32 is under notch 31 of slide 29. The slide is immediately pressedrearward by a spring thereby slightly rocking the. bell crank 23. Whenthe segment 25 again moves upward it will carry slide 29 with it byconnecting the notch 31 and projection 32 and thus moving the segment 22until the pawl 27 abuts theend of the depressed key. The continuedmotion of segment 25 serves to rock the bell crank as pawl 27 is stoppedby the key to disconnect the slide 29 from hole 72 in the bottom thereofsegment 25. The forward movement of slide 29 serves to move a projection45 thereof into one of a series of depressions 46 on the key framethereby locking the slide 29 and segment 22 in a position depending onthe key depressed. The segments 22 are each connected to intermediategears 47 which are in turn connected to indicators 49. The gears 47 arerigidly mounted on a series of nested sleeves 50 which run through tothe left hand end 'of the machine and are there provided with pinions.It will be clear that the indicators 49 and the pinions on the outer endof nested sleeves 50 move continuously with segments 22, so that in thenormal operation of the machine the indicators and sleeves which havebeen set are first returned to normal position as above described andthen reset in accordance with the new transaction.

Total retaining devices.The total retaining devices are shown in detailin Figs. 19 and 20 from which it will be seen that each total retainingdevice is provided with a plurality of denominational elements hereshownas rack slides 60. These slides are normally locked in position bya latch 61 pivoted on rod 62 and spring pressed to latching position bya spring 63. The rear end of the latch 61 as indicated at 64 rests on anelevated portion 68 of three indentifying slides 65 which slides areshown as of different lengths in Fig. 19. Springs 67 are provided onefor each denominational and for each identifying element and serve tonormally position same to the left in these figures. It will be clearthat the five denominational slides are positively locked and that tounlock them the identifying slides must be moved rearwardly until theelevated portions 68 thereof are carried under the rear end 64 of thelatch. A depression 69 is provided in each identifying slide and whenend 64 of the latch. It will be clear that it is practically impossibleto so move the elements 65 that all three would be under the rear end ofthe latch atthe same time, but mechanism is provided in the machine forgears 48 on readily accomplishing this purpose. Aperf tures 70 one foreach slide are provided in one end of the device and these are the onlyopenings in the casing 71 except a small through which the releasingdevice is adapted to move. The casing is solid except for these fewsmall apertures and it is to be noted that 1 for adjusting front of theslide 71 being held &

even if slides are moved so that the de-' pressions 69 are all under therear end of the latch that the latch is still spring pressed and servesto prevent movement of the denominational slides @until a rod isinserted through the aperture 72 far enough to engage a depression 7 3in the latch 61 and raise the same. At the end of the total retainingdevice distant from the aperture 70 are provided projections 74 forholding a plate bearing the clerks or customers number or any otheridentifying information. A

Controlling mechanism.The mechanism the total retaining devices is bestshown in Fig. 4:. At figure a retaining device is shown broken away andentered in the machine. In front of the apertures 7 O of the retainingdevice are a series of slides 71 guided ward ends by pins 7 2 engagingslots 7 3 in said slides. At their rear ends the slides pass through theactuating bar 745* which is part of a frame .including arms 75. On eachside of the arm 74* are springs 7 5 and 76 for each slide 71, serving toretain the slide in the middle position. Each slide 71 is provided witha slot 78 in which rides a pin 79 on a printing segment 80. The'segments80 there bein one for each slide 71 are each provided with rack teeth 81adapted to engage with register wheels 82 when the same are depressed.The-frame including arms 7 4 and is adapted to be reciprocated forwardlyof the machine this being accomplished by a cam groove 83 in a disk 84mounted rigidly on and rotated by a shaft 85. The frame has ananti-friction roller 86 engaging the cam groove 83 and it will be seenfrom the shape of the groov'e that the frame will be moved firstforwardly and then reversely twice at each operation. .This movementevidently tends to move all the slides 71 in the same manner. flash 86is normally in in such position against tension of a spring 87 connectedto an arm 88 which carries the flash, by a cam 89 also carried by shaft85. This cam 89 engages theanti-friction roller 90 on the rear end ofarm 88 in the normal position of the mechanism but when shaft 85 isrotated cam 89 is carried from over roller 90 and the flash can thenmove out of the path of slides 71. These slides then come forward untilstopped by the denominational elements of the total retaining devicethereby setting up on the printing segments the amount of the entry onsaid retaining device and also adjusting the racks 81 to the sameextent.

Printing segments 80 and controlling slides therefor are also providedfor the identifying elements 65 of the total retaining device but itwill be remembered that the identifying elements are not locked againstmovement so that when the slides 71 the right of this at their for-,

' wardly the cam 103 and reversely twice at each operation printingreturn of racks 81 to normal add on register 82 the amount previously1n-' dicated by the denominational slides 60. It.

connection between arm 7 4 therefor are moved forwardly they serve topushthe slides 65 against the tension of their springs 67 until thedepressions 69 are nearly under the rear end 64 of latch 61. As abovestated however the depressions 69 are not in line and mechanism istherefor necessary to bring them into set line before the latch 61 maybe released. This mechanism is shown in Figs. 12 and 13 and it will beseen that in Fig. 12 the clerks printing devices 80 are set in slightlydifferent positions it'being assumed in this figure that the slides 71have moved forwardly and have thereby moved the identifying'slides 65 asfar as possible. The alining pawl 100 is pivoted on a shaft 101 and alsoon this shaft is an arm 102 adapted to be operated by a cam 103 on adisk 101 carried by and rotated with shaft 85. The arm 102 is pressed bya spring 105 to withdraw the alining arm 100 from the rack teeth 81.When the shaft 85 is rotated and all the slides 71 thrown forserves toraise arm 102 thereby lowering arm 100 and serving to alinetheidentifyingprinting devices and vice directly under the rear end 64of the to force the slides 65 of the total retaining de latch 61. Thedenominational slides 60 are however still latched and are not unlatcheduntil the arm 61 is positively raised.

Registering mechanism.-The main operating shaft 36 previously referredto carries asshown in Fig. 1 a cam disk 106 having a cam groove 107therein. this cam groove is an anti-friction roller 108 carried by thebell crank lever 109 pivoted at 110 the forward arm of which carries arod 111 on which are mounted the register pinions 82. These registerpinions have no numbers thereon though they might have, and consistmerely of accumulating gears provided with transfer pins 112. When themachine is operated shafts 85 and 36 are rotated and the rotation of thefirst mentioned sets the racks 81 to a position depending on theposition of the denominational slides 60 but the register 82 is notmoved at this time. When the portion 83* of cam groove 83 reaches theroller 86 it will be clear that the frame arms 7 4 and 75 will bereturned to the position shown in the figure. This will also cause thereturn of segments 80 and racks 81 to normal position but at this timethe roller 108 has moved upwardly as will be seen from the shape of camgroove 107, and the register pinions 82 have thereby been depressed intomesh with racks .81. o It will be clear that the position will willreadily be seen that the purpose of springs 76 and "('5 is to provide aflexible and the slides 71 so that the arm 74f may be given a fullstroke in either direction without necessarily the arm 126, whichelevates the latch 61.

The arm 126 is yieldingly supported by the spring 127 carried in anaperture 128 of a piece 129. The piece 129 is provided with a pin 130which engages a slot in an arm 131 pivoted at 132 and normally drawndownward by a spring 133. To shaft 132 is fast an arm-137 carrying a pin135 which rides in a slot 136 in a vertically movable bar 137. This baris supported on the machine frame by headed pins 138 riding in a slot136 and an additional slot 136. Connected to the slide 137 by the pin139 mounted thereon is a lever 140 pivoted on a pin 141 and at its rearend straddling loosely the shaft 85. A vertical projection 142 of thislever 140 is provided with an anti-friction roller 143 riding in a camgroove 144 out in-disk 104 which as previously stated is rotated byshaft 85. It will be seen from the shape of the groove 144 that when'theportion 144 thereof reaches the roller 143, the lever 140 will berocked, thereby lowering the bar 137 and raising the arm 126 until itabuts and raises the latch 61 to release the denominational slides 60.This release however does not occur until the printing segments 80 havebeen set and have been returned to normal position in mesh with counterpinions 82. When the denominational slides 60 are released as describedthey immediately move under tension of their spring 67 to position shownin Fig. 19 which is the zero position of the device.

Register operating mechanism-It is next necessary to enter on theregistering device the new transaction. As before stated the nestedsleeves 50 on Fig. 3 are moved in accordance with the amount of the saleor other transaction and in' so moving serve to adjust, first, reverselyto normal position and then forwardly to the desired position a seriesof pinions mounted on said nested sleeves. These pinions are indicatedby numeral 151 on Fig. 6 and all except the one on the innermost sleevemesh with pinions 152 also mounted on nested sleeves 153. On the otherend of said sleeves 153 is a second series of pinions 154 meshing with aseries of gears 155, the gears 154 and 155 being also shown on Fig. 4.The object in using the additional set of nested sleeves and pinions isto procure a reversal of the order of pinions 155 as compared withpinions 151. In the machine the banks of keys and the segments 22 are inascending denominational .able at will. It will be order from right toleft so that the pinions 151 are in reverse order. It is howeverdesirable that pinions 155 same arrangement as the segments 22 and thisis accomplished by the pinions 152 and 154 on the nested sleeves 153. Itwill be easily seen that the pinion 151 of lowest denomination does notneed a pinion 152 or sleeve 153. Y

The pinions 155 are each adapted to mesh with two horizontal rack barsone above the pinion indicated by 156 and one below the should have thepinion marked 157. These rack bars extend forward and each have a rackon the lower side thereof at 158 adapted to mesh separately with theregister pinions 82.- The racks are all supported at their forward endsby the rod 159 which is laterally shiftclear'that the movement of racks156 is in a direction opposite to the movement of racks 157 and that todetermine whether an amount shall be added to the register 82 orsubtracted therefrom it is only necessary to provide means for causingeither set of racks to mesh with the register at will. The mechanism isnormally so adjusted that the adding racks 156 are directly over theregister pinions 82 so that the amount entered in the machine is addedto register 82 and when it is desired to sub tract, the amount racks areshifted by the lateral movement of rod 159 to bring the subtractingracks 157 over the pinions 82. As previously stated the segments 22 anddevices operated thereby remain in set position between operations ofthe machine and at any operation are restored to normal position andthen are readjusted to their new position. This clearly also applies toracks 156 and 157 though they are shown in Fig. 4 as in normal or zeroposition. It will be clear that the register pinions 82 must be droppedout of mesh with the racks 157 be fore such restoration of the racks tonormal takes place and that the register pinions must be again placed inmesh with the racks before the racks are readjusted to their newpositions. When the racks are so adjusted the register pinions 82 arealso moved and it being remembered that the pinions 82 have beenpreviously set by the racks 81 to an amount depending on the position ofdenominational slides 60 and equal to the total amount on the totalretaining device, it will be seen that the register pinions 82 are nowset to the total including the new transaction. Broadly speakingtherefore if the register pinions 82 are now depressed into mesh withsegments 81 and the slides 71 thrown forwardly the register 82 will berestored to zero and when so restored will stop the slides 71 in aposition depending on the total amount which the register had indicated.The forward movement of slides 7 ll evidently serve to move thedenominational slides 60 of the total retaining device and will therebyset such slides to a po sition indicating viously on the slides added tothe amount of the new transaction. v

Transfer deoicea-Jt is to be noted however that as two amounts have beenadded on the register a transfer may be necessitated. Inasmuch as racks156 and 157 are positively connected together through pinions 155, itwill clearly be necessary to provide only one set of transfer devicesand it is to benoted that this one set provides for a transfer in eitheran adding or a subtracting direction. The mechanism shown is adapted tomove the racks an additional step and in this embodiment the position toengage the adding racks 156. Directly over racks 156 are bars 161connected at their rear ends to levers 162 pivoted on a rod 163 andcarrying at their lower ends anti-friction rollers 164. These rollersare adapted to be engaged successively in the usual manner by cams 165rotated with shaft 36 so that the bars 161 are given a forward movementat each opera- ,tion of the machine and are returned to normal positionby springs 166 connecting a frame rod 167 with hooks 168 carried by thesaid bars 161. Each bar also carries at its forward end a transfer pawl169 normally held up by pins 170 mounted thereon which rest on trippawls 171 carried loosely by the rod 159. These trip pawls of which oneis shown separately in Fig. 11 have depending projections 172 in'thepath of pins 112 on the register pinions 82. It will be clear that asthe register pinion is rotated in either direction its pin will strikethe trip pawl 171 and rock the same against the tension of a leaf spring17 2 carried by each pawl tending to return the same to verticalposition from either direction. When the trip pawl 171 is so rocked thetransfer pawls 169 drop, being moved by springs 173 into the teeth ofthe ratchet 174 of which there is one on each adding bar 156. When theshaft 36 is further rotated cams 165 strike the rollers 164 and pushforward the bars 161 thereby also moving the racks 156 and 157 anadditional step. It will be seen that no matter whether the adding rack156 or the subtracting rack 157 is in'gear with the register pinion 82the additional step of movement'of the rack will cause the properadditional step movement of the register. If racks 156 are in gear withthe register it will be easily seen that the additional forward stepthere-- of will cause the proper transfer movement of the registerwhereas if racks 157 which aresubtracting racks are in gear with theregister pinions the additional movement of racks 156 will cause anadditional movement of racks157 which will reversely rotats-the registerpinion 82 for a subtracting-v the total of the amount we transfer deviceis in transfer. It is of course necessary in view of the fact thattransferring movement is to be given to pinions 155 by racks 156 that aloose connection be provided between the pinions 155 and their operatingdevices. This is illustrated in Fig. 8 where the pinion 155 is shown asconnected'to the operating devices. It will be seen that to give atransferring movement merely tensions spring 179 and that th's springserves to retract the operating racks their additional step as soon asthe transfer pawls 169 are raised.

Subtracting mechanism.-It remains to be explained how the racks areshifted laterally to cause either set to mesh with the register inions.This is best shown in Fig. 7 and as will be seen the register pinions 82are normally directly under the adding racks 156 and out of relationwith the subtracting racks 157. It will be remembered that the racks areall carried by rod 159 and this is given a lateral movement by bevels182 carried on the shaft and 183 carried at the top of a curved arm 184shown on Fig. 15. This curved arm 184 is carried by headed pins 185moving in slots in the bar and is also provided with three cam slots 186andtwo straight slots 187 in which are adapted to move pins 189 carriedby each of the special keys. As shown on both of these figures (Figs. 7and 15) are provided five special keys which reading from top to bottombear checks reading respectively Void, Bill, Received on Account,Charge, Paid Out. The Void key is intended to be used when goods arereturned for any reason, the Bill key is used when the customer desiresa statement of account or when the proprietor wishes to learn the amountof any total retaining device, Received on Account key is used when acustomer pays in money on account, the

, Charge key when amount is to be charged to a customer and the Paid Outkey will be used when money is paid from the cash drawer by a clerk. Ofthese keys it is clearly necessary that the Void key, Received onAccount key and the Paid Out key should cause a subtraction of theamount from the register, whereas the Charge key is desired to cause anaddition of the amount. This isevidently accomplished by the cam slots186 for the Void, Received on Account and Paid Out keys as it will beseen that the depression of any one of the three said keys will raisethe curved bar 184 thereby causing the bevel 183 to engage bevel 182 andso slide the rod 159 laterally to an extent suflicient wide enough toengage the adding racks 156 in either position. A spring 190 extendsbetween the on a rod 159 and serves to return it to the position shownin Fig. 7 to engage the adding racks with the register.

rintz'ng mechanism.-It was previously stated that the register pinions82 first have the amount indicated by the denominational slides 60 ofthe total retaining device added thereto and then are readjusted inaccordance with the new transaction by the adding or subtracting racksand the transfer mechanism. Following this slides'71 are again 221 andthrown forwardly this time with segments 81 in gear with registerpinions 82 until the said pinions are returned to normal position. Itwill be clear that at this time the printing segments are set to the'total of the previous amount on the total retaining device and theamount of the present transaction. It is now desired to print the totalamount and mechanism for so doing will be next described, referringparticularly to Figs. 4

and 13.

The machine is constructed to print at ,each operation on a detail stripwhich is retained in the machine and on a check which is fed out of themachine or an inserted slip. The detail strip 200 is carried on a roller201 from whence itis led from pins 202 and 203 to a winding roller 204.,This roller has a gear 205 with the teeth of which engages the drivingpawl 206 pivoted to an arm 207 which is carried on a shaft 208 alsosupporting the winding roller 204. A spring 209 connects the pawl 206 tothe arm 207. Also connected to arm 207 is a link 210 which as shown inFig. 13 has a slot 211 in the rear end thereof. The main shaft 24 whichwas previously stated to be oscillated at each operation carries an arm212 havin a pin 213 riding in said slot 211. It will be seen that whenthe shaft 24 is oscillated the pin 213 will move through slot 211 andthat when it reaches the rear end of the slot the further motion of thepin will move the link 210 and draw pawl 206 rearwardly to rotate thewinding roller 204 sufficiently to feed the str1p. When the shaft 24returns to normal positlon the last increment of motion thereof willcarry link 210 forward whereupon the end of the pawl 206 rides idly overthe succeeding tooth of the gear 205. The ex tent of this feed canclearly be regulated by changing the length of the slot 211. The gear205 meshes with-the second gear 213 carrying a roller 214 for pver aseries of rollers 216 so that the ink ribbon is also fed slightly ateach operation.

The check strip 220 is carried by a roller passes downwardly through apivoted' chute 222 from whence it passes between printing and feedingrollers 223 and 224 and over'a knife blade 225 to the printframe pieceand a collar 191 ing a' consecutive number v tinue the check feed andfeeding an ink rib-- bon 215 which passes around this roller and at thefront of the machine is adapted to be issued at the side thereof and tothis end-I provide a carrying table shown in Figs. 1, 4 and 10. Thetable is normally withdrawn rom the machine as indicated in F ig. 1 butis adapted to be drawnv into the machine at each operation, and when sodrawn in it provides a support for the check strip 220 as it ,is fedforwardly. The slot 226. in the table serves to allow the feed of thecheck str'p. The feeding and printing roller 224 has any desired matterthereon for printing on'the check such for example as an advertisementof the proprietor, means for printand the date. A small roller 227 isprovided which may carry any matter desired to be changed frequentlysuch for example as Your Bill is Due or any other desired matter. Theserollers 223 and 224 are givena complete rotation at each operationof themachine being connected through a gear train shown in Fig. 15'to a gearon shaft 36.

An ink roller 228 is supported on arms fastened to the pivoted checkcarrying frame 222 so that when no check is to be issued the chute maybe rocked rearwardly so that the type on roller 224 will not beunnecessarily gummed with ink. It is desired that when a chargetransaction is to be entered in the machine and on a total retainingdevice the check. In this a slip be used instead of case it is desiredto throw off or disconthis is provided for as shown in Figs. 4 and 15 byan arm 231 connected at its rear end to an arm 232 which serves tooscillate the eccentric sleeve 233 which carries the roller 223. Thisarm 231 is supported at its forward end by a pin 234 passing through aslot in said arm and is returned to normal position by a spring 235connecting said pin 234 to a pin on the arm 231. The forward end of arm231 is curved as shown at 232 so as to be in the path of pin 189 of thecharge key. It will be evident that when the charge key is depressed theeccentric sleeve 233 will be rocked enough to carry roller 223 away fromroller 224 so that although the rollers are rotated by the operation ofthe machine no feed of the check takes place. As above stated the checktable 240 is adapted to be injected into the machine at each operation,but if a charge transaction is to be entered the table must be pushed inby hand before the machine is released as willbe described. The checktable 240 is supported by arms 241 sliding on horizontal rods 242. Asshown in Fig. -18 one of these rods is provided with a sleeve 243movable with the arm 241 and carrying a pin 244 against which abuts thelever 245 pivoted on a pin 246 and having at its rear upper end ananti-friction roller 247 moving ina cam lever 245 isrocked groove 248 ina cylinder 249 carried by a' shaft 250 which is given a completeoperation at each rotation of the machine through a gear 251 carriedthereby meshing with a gear 252 on the main shaft 36. A spring 253connected to the'main frame and to a pin on sleeve 243 tends to returnthe check table to its outward position and a latch 254 pivoted on a.pin 255 and pressed by a spring 256 against a pin 257 is adapted toengage pin 244 on a sleeve 243 when the check table has been moved intothe machine. From this description it will be evident that the checktable may be moved manually into the machine carrying pin 244 into aposition where it is latched by pin 254. During the operation of themachine, by the cylinder 249 far enough to force the latch 254 backreleasing pin 244 so that when the lever 245 returns to the position ofFig. 18 the table will also move outwardly under tension of spring 253.

If however no slip is to be used but a check is desired the operation ofthe machine will rock lever 245 and force the check table into themachine in position to receive the check and to carry the checklaterally out of the machine.

To print a record from the segments the mechanism shown in Figs. 4 and 5and 13 is employed. It will be remembered that the table 240 is drawninto the machine at each operation and the check fed thereover. Animpression is desired on the check and after the impression has beenmade and the table moved outwardly the impression on the strip isdesired. To-accomplish this impression taking a platen and a means forimpressing it against type segments twice at each operation areprovided.

Referring first to Fig. 13 it will be seen that main shaft 36 carries acam 260 adapted to raise an anti-friction roller 261 on a link- 262which straddles the shaft 36 and which Y is connected at its lower endto a platen arm 263 carrying a platen 264. This arm is pivoted at 265and is normally spring drawn in a direction to force the platen againsttype segments 80 bv the spring 266. Also pivoted at 265beside the platenarm 263 is a second arm 267 spring drawn in a manner similar to theplaten arm by spring 268 and having a pin 269 directly over saidplaten'arm 263. At the forward end of the arm 267 is a projection 268which when the forward end of the arm is depressed is adapted to passunder and be held by a latch- 269 pivoted on the pin 270 and having adepending projection 271. Directly in front of the depending Fig. 5 is ale er 272 connected at 273 with a second lever 274, these levers 272'and 274 being pivoted at intermediate points as shown. At one endthereof, leverv 274 has a curved part 275 in the path of the pin 276rojection 271 as shown in carried by the check table. When shaft 36 isrotated the cam 260 will raise link 262 thereby depressing the platen264 and also depressing the projection 268 and arm 267 until it islatched by latch 269". When the high point of cam 260 passes from underroller 261, spring 266 will immediately elevate the platen 264 and forceit against the type segments 80 thereby making an impression on thecheck or slip whichever is used. 1.5 When the slip table is forcedoutwardly by spring 253 the pin 276 carried by the sleeve 243 willengage the end 275 of the lever 274 and move rearwardly dependingprojection 271 and latch 27 0. This releases arm 267 which immediatelyoscillates under tension of its spring 268 and forces a pin 269 upwardlyto strike the lower side of the platen arm 263 so that the said platenarm will again be forced against the type segments 80 this time printingon the detail strip 200.

Ze'r'o stop for register.-It has been previously stated that theregister pinions 82 are reset to zero by the racks 81 for the purpose ofdetermining the final position of the denominational slides 60 of thetotal retaining device. It is necessary to provide some means forstopping the pinions when they reach their normal position and thismechanism will now be described, referring to Figs. 7 and 9. It will beremembered that the rod'lll carrying register pinions 82 is raised andlowered twice at each operation, to bring the pinions into mesh with thesegment gears 81. The rod 111 supporting the register pinions is slitlongitudinally and two oppositely beveled bars 301 and 302 are insertedin the longitudinal slit.

Bar 301 is fast-to the rod 111 but bar 302 is loose therein and extendsbeyond the mg ister pinions having at its extreme end an anti-frictionroller 303 which rides in an oblique slot 304 in a bracket 305. In theupper position of rod 111 the bar.302 is as shown in Figs. 7 and 9forced to the right completely filling up the slit in the bar 111. Whenhowever the register pinions are depressed the roller 303 rides down thecam slot 304 forcing the beveled bar 302 to the left and therebyallowing the lower edge of 115 said bar to rise slightly. Each registerpinion 82 is provided with a zero setting pawl 306 pivoted thereto on apin 307 and pressed by the spring 308 around theaxis of the pinion. Inthe upper position of the rod 111 1 the pawl 306 may ride past the pointin which it is shown in Fig. 9, but when the register pinions arelowered and beveled bar 302 raised relative thereto the said bar movesback within the slit in bar 111 thereby fu r- 1 nishinga positive stopfor the pawls 306 and so setting the pinions 82 positively atzeroposition. As at this time the pinions 82 are in gear with segments 81the segments are positively stopped in a position dependent 139 on theamount which the register pinions had been moved from normal position.

A collar 309 is shown as around rod 111 but this is a part oftheregister pinion which is counter sunk to provide a place for the zeropawl 306. This collar 309 does not therefore impede the movement of pawl306. It will be remembered that pinions 82 are depressed in the firstpart of the operation to engage segments 81 but at this time thesegments invariably move the register pinions forward and the beveledbars 301 and 302 offer no obstruction to this movement.

Locking deoicea-1t is desirable that mechanism should be providedpreventing an operation of the machine until one of the total retainingdevices has been injected therein. It is also desirable that when theretaining device has been so inserted it should be locked in positionuntil the end of the operation. Referring to Fig. 4 it will be seen thatthe total retaining device has on the top thereof a cam 311 having anotch 312. When the retaining device is pushed into the machine the cam311 rides under and elevates the arm 313 on a shaft 314, said arm 313having a projection 316 which finally drops into the notch 312 of thecam 311. On shaft 314 is shown in Fig. 15 a second arm 315 having a pinand slot connection 317 with a curved. bar 318. This bar is carried byheaded pins 319 and 320 passing through a slot 321 in said bar and hasat its upper end a spring connecting a pin thereon to a pin on the mainframe and tending to raise the bar 318 to the position shown in thefigure. A projection 322 of bar 318 normally rests against an arm of abell crank lever 323 pivoted to a stub shaft 324 and carrying a pawl325. he pawl is pivoted at 326 to the arm 323 and is normally drawn by aspring 327 connected to arm 323 so that a pin on the said arm 323 isagainst the edge of a cut away portion of the pawl. Just below the pawlthe arm 323 is cut away at 328 and the pawl as shown projects slightlyover the cut away part. As shown in Fig. 2 the stub shaft 324 supportsthe other arm of the bell crank lever 323 which has projecting therefroma lug 329 normally .in front of a lug 330 on the gear 38. The bell crank323 is curved at its rearward end and has connected thereto a spring 331fastened to the main frame. Carried by gear 37 is an antifriction rollerIt will be clear that normally the projection 329 of hell crank 323prevents movement of the operating mechanism. When the total retainingdevice is inserted the cam 311 carried thereby moves under arm 313 andraises the same thereby depressing the arm 315 and so carrying down thecurved bar 318, the upper end 322, which is moved far enough to pass thepoint of pawl hen the notch 312 reaches the projection 316 of the ar,313 the said arm may drop slightly thereby allowing the curved bar 318to rise slightly when the projection 322 rocks the pawl 325 to entirelyuncover the cut away portion 328 of the arm 3 23. WVhen this is done thespring 331 ma rock the bell crank 323 and withdraw the projection 329from in front of projection 330 thereby unlocking the machine. It willbe seen that it is not merely the pushing in of the total retainingdevice which unlocks the machine but it is the carrving of projection322 of curved bar 318 past the cut away part 328 and then allowing it torise again which unlocks the machine. A mere implement inserted in theaperture where the retaining device is put would not serve to operatearm 313 in such a way as to release the mechanism.

As shown in Fig. 10 the total retaining device has a struck up lug 336on the side thereof and when the device is completely entered in themachine the lug 336 passes behind the bar 337 carried by an arm 338.This arm as shown in Figs. 13 and 14 has a projection 339 at its rearend directly over a bevel 340 on the vertical bar 137 previouslyreferred to. It will be remembered that lever 140 is rocked to raise theplunger 126 and to release the same, near the end of the operation. Itis also adapted to move the bar 137 upwardly beyond its normal positionafterward, as will be seen from the part of the cam groove 144 marked144 and this is used to release the total retaining devices. When bar137 moves under theend 339 of arm 338 thereby carrying the samelaterally enough to withdraw the pin 337 from in front of lug 336 of thetotal retaining device. A plunger 341 is shown on Fig. 4 pressed by aspring 342 outwardly so that when the total retaining device is releasedthe plunger 341 will move outwardly and ejectthe total retaining deviceon to the curved table shown on Fig. 1. It is however necessary that arm313 should be raised to carry projection 316 away from notch 312 at thistime as this will also serve to hold the retaining device. It will beseen that as gear 37 shown on Fig. 2 rotates, the roller 332 carriedthereby will raise the rear arm of bell crank 323 to carry projectlon329 again in front of projection 330, and the roller 332 is sopositioned that the arm 323 is raised farther than the position 1n whichit is shown. This additional movement will evidently rock the forwardarm of the bell crank 323 rearwardly past the p0s1 tion in which it isshown in Fig. 15. Carried by the forward arm of bell crank 323 is acurved arm 351 having an anti-fnctmn roller 352 which abuts a curvededge of the bar 318. In the normal position of the mechanism the roller352 merely touches the bar 318 but when the additional rearward movementof lever 323 is given the roller moves upward its bevel 340 352 willforce-bar 318 downwardly enough tocarry the projection 316 on the end ofarm 313 away from the notch 312 and will thereby release the totalretainingdevice so that it may be pushed outwardly by plunger 341.

It may occasionally be desired to release and allow the ejection of aninserted total retaining device Without an operation of the machine asfor example in case a Wrong retaining device was inserted. To accomplishthis function a projecting releasing lever 353 is provided as shown onFig. 2 pivoted on a pin 354. A pin 355 mounted on arm 353 moves in aslot of a lever 356 pivoted at 357 and normally drawn by spring 358connecting the lever to a bracket on a main frame. The upper end oflever 356 is directly over a projection 359 of an arm 360 carried bythestub shaft 324 which also carried bell crank lever 323. When the 332 ongear 37.

retaining device.

arm 353 is depressed the bell will be rocked against the tension and itsupper end engaging the projection 359 of arm 360 will produce preciselythe e'flect produced by the roller That is it will rock bell crank lever323 past its normal position and so release the total retaining device.A projection 361 on the bell crank lever 356 will when arm 353 isdepressed pass into a cut away portion 362 of a disk 363 carried by thegear 39' thereby locking the operating mechanism while the releasingdevices are in use. It hasbeen stated that a depression of projectingarm 353 will release the total retaining device but it will beremembered device is held by pin 337 as well as by projection 316 of arm313. It has been described how the arm 313 is released and on 13 it willbe readily seen that when projecting arm 353 is rocked a second arm 353also carried by shaft 354 is depressed. This arm 353 carries anantifriction roller '353 in a slot 353 of a bell crank lever 353 Thislever is pivoted on a pin 353 and at its upper end has a bevel 353 inaposition such that when the bevel is moved forwardly it engages the rearend 339 of the arm 338 thereby. withdrawing pin 337 from in front of lug336 on the total projecting crank 356 of spring 358 shown on Fig. 10. Itmay be noted that a depression of arm 353 will in the patented machineserve to release any depressed key as well as to release the totalretaining device but that is no part of the present invention andis notshown herein.

It has been said that the machine is normally locked and is released bythe inser tion of-a total retaining device. In case a chargetrans'actibnis to be entered in the machine it is desired to compel-the insertionand check table as a slip is'used in connection with this classof'transaction.

371 to a pm on in Fig. 16 the pivot 372 projects through surrounding thepin is so This bevel 353 is also and means are employed for preventingthe release of the machine when the charge key is operated even thoughthe proper total retaining device has been inserted until after thetable has this mechanism being shown in Figs. 15 and 16. The charge keyis the second key fromthe bottom and its pin 189 is adapted whendepressed to engage and rock an arm 371 carried on a pin 372 main frame,this arm being drawn forward by a spring 373 connecting a pin on arm themain frame. As shown a frame bar and coiled spring 374 normally forcingthe arm 371 but the movement of arm, 371 is limited by a pin 375 passingthrough the pin 372. The arm 371 is directly in front of the lower end376 of bell crank 323 which it will be re- 35 membered is forcedforwardly by a spring to release the mechanism. When the charge key isdepressed arm 371 will be rocked rearwardly and will abut and restorethe bell crank 323 to its normal position. This however will not releasethe projection 322 as it will still be held by pawl 325. To unlock themachine in this case it is necessary to press. in the slip table. Thesupporting sleeve of said table carries a pin at the end of its inwardtravel is in position to engage and shift laterally the arm 371 againstthe tension of its spring 374. Such lateral shift of will then moveforward under its spring and release the machine.

As shown in Fig. 1 and as previously stated one of the special keys is aBill key. This key will be used sired to print a statement of the amountentered onany retaining device and it produces no effect on the machineexcept to controla printing device to impress the letter B or some othercharacter on the record. As 110 of course no amount keys should beoperated in connection with this Bill key an interlock is provided therebetween. In this type of machine the amount keys 21 as shown in Fig. 17have a beveled inner end which when 115 a hole in which a asses.
